Description

一种设置最大带宽的方法、 装置与系统
技术领域
本发明涉及通信技术领域, 特别涉及一种设置最大带宽的方法、 装置与 系统。
背景技术
图 1 为现有技术的 EPS (Evolved Packet System, 演进分组核心网系 统) 架构示意图。 如图 1所示, EPS主要包含移动管理实体 MME、 服务 GPRS支持节点 SGSN、 服务网关 Serving Gateway、 分组数据网关 PDN Gateway以及策略与计费功能实体 PCRF等逻辑功能体。
其中: SGSN负责 UE从 UMTS陆地无线接入网 UTRAN或者 GSM edge无线接入网 GERAN接入时的 NAS信令处理以及漫游、 跟踪等功能; MME负责 UE从演进的 UMTS陆地无线接入网 EUTRAN接入时的 NAS信 令处理以及漫游、 跟踪等性能; Serving Gateway (SGW)负责本地的移动性 锚点和 3GPP系统内部的移动性锚点以及合法监听相关信息; PDN Gateway (PGW)则负责策略执行和计费以及合法监听相关功能。 PCRF负责策略决 策、 指定和 QoS以及计费相关的策略。
图 2是现有技术中 GPRS (General Packet Radio Service, 通用无线分 组服务) 的网络架构示意图。 其中, SGSN提供对用户从 2G或者 3G接入 时的移动性管理、 安全管理、 接入控制和路由选择能力; GGSN负责 GPRS 网络与外部数据网的连接, 可以连接到多种数据网, 如 Internet 企业网、 X.25 网等, 其功能与 PGW类似, 但是不具有 PGW支持的多接入能力。 在 GPRS系统里, 网关 GPRS支持节点 GGSN也可以和 PCRF交互 (图中未画 出) 。 不论是 EPS还是 GPRS系统, PCRF逻辑功能都是可选的。
图 3为现有技术中移动台 MS激活首次上下文的过程, 通过该过程, MS可以分配到一个 IP地址, 从而实现 MS的数据业务。 具体地, 该过程包 括: S30K MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含首次 上下文的最大带宽;
5302、 S4 SGSN向 SGW发送创建会话请求, 携带 APN (Access Point Name, 接入点名称) AMBR (Aggregate Maximum Bit Rate, 累计最大带 宽) , 其中 APN AMBR由 MS请求的首次上下文最大带宽生成; 也可以由 S4 SGSN从 HSS获取的 EPS签约 QoS profile生成, profile里含有 APN AMBR参数, 此时可以忽略 UE请求的最大带宽;
5303、 SGW向 PGW发送创建会话请求, 包含 APN AMBR;
S304, PGW向 PCRF请求建立 IP-CAN会话, 携带 APN AMBR;
S305、 PCRF根据用户签约以及运营商策略, 授权 APN AMBR, 返回
IP-CAN会话建立响应;
5306、 PGW返回创建会话响应消息, 携带 APN AMBR以及分配的 IP 地址;
5307、 SGW向 S4 SGSN返回创建会话响应消息;
S308、 S4 SGSN指示 RNC建立无线承载;
S309、 S4 SGSN向 MS返回首次上下文建立响应消息, 携带协商后的 首次上下文最大带宽以及分配的 IP地址, MS可以使用该地址来进行数据业 务。
版本号为 3GPP release 7 以前的终端不支持协商后的最大带宽超过 16M, 而之前的无线接入网, 比如 GERAN, 其无线网络提供的最大带宽为 160kbit/s, 所以不会出现问题。
随着新的接入技术如 HSPA+等接入技术的出现, 运营商可以提供的最 大带宽已经可以达到 21M甚至更高, 也就是说, 图 3中 S309返回给 UE的 授权最大带宽可以超过 16M, 而在这种情况下, 3GPP release 7以前的终端 会拒绝 PDP上下文建立 (如 S310所示) , 导致 3GPP release 7以前的终端 无法实现数据业务。 但是, 如果网络统一授权的最大带宽都小于 16M, 则使用 3GPP release 7以后终端的用户就始终无法享受到超过 16M的带宽, 使得部署了 HSPA+ 网络的运营商无法充分利用网络资源。

具体实施方式
当运营商部署 HSPA+网络以后, HSPA+支持大于 16M的接入带宽, 而 部分终端仅支持小于 16M 的带宽参数, 如果对这些终端授权的带宽超过 16M, 则这些终端无法激活首次上下文, 从而无法实现数据业务; 如果对所 有终端仍按照小于 16M授权, 则使用新终端的用户无法享受到超过 16M的 带宽体验。
本发明实施例提供一种设置最大带宽的方法、 装置与系统来解决上述问 题。 本发明实施例的技术方案, 通过获取用户设备 UE的带宽支持能力, 来 为 UE授权与该能力匹配的最大带宽。 该带宽支持能力可以是以 UE的版本 信息来体现, 如 3GPP release 7之前的版本不支持协商后的最大带宽超过 16M, 而之后的版本则支持协商后的最大带宽超过 16M; 另外, 后续实施 例中将以 UE的版本信息来表示 UE的带宽支持能力, 但是实际上还可以采 用其他信息来表示 UE的带宽支持能力。 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。 实施例 1 : 本实施例提供一种设置最大带宽的方法, 图 4为该方法的整体流程图。 如图 4所示, 该方法包括:
S40K 获取 UE的带宽支持能力;

可选地, S401具体包括: 从 RNC中获取 UE的带宽支持能力; 或者从 UE发送的激活上下文消息的 PCO选项中获取 UE的带宽支持能力。
可选地, 为了节约信令资源, 该上报的歩骤具体包括: 缓存已上报的
UE的带宽支持能力; 如果获取的 UE的带宽支持能力已经上报, 则不再上 报; 反之, 上报获取的所述 UE的带宽支持能力。
可选地, 所述带宽支持能力包括: 用于指示所述 UE是否支持特定带宽 的信息或者 UE支持的版本信息。 该特定带宽可以为 16M。
根据 UE带宽支持能力的不同, 该方法可以具体包括以下几种情况:
(1)当获取的 UE的带宽支持能力小于所述特定带宽, 或者 UE支持的版 本是某个特定版本之前的版本, 或者获取的 UE的带宽支持能力未知, 或者 未获取到 UE的带宽支持能力时; 为所述 UE授权不高于所述特定带宽的最 大带宽。
(2)当获取的 UE的带宽支持能力大于所述特定带宽时; 根据签约信息和 /或运营商策略为 UE授权最大带宽。

本实施例的方法, 通过获取 UE的带宽支持能力来为 UE授权与其能力 匹配的最大带宽, 能够满足不同类型终端的带宽需求, 充分利用了网络资 源。 这种带宽协商的机制, 有效避免了由于授权的最大带宽高于终端支持的 带宽而导致的终端业务无法建立的问题, 以及由于授权的最大带宽小于终端 支持的带宽而导致网络资源浪费的问题。
实施例 2: 本实施例提供一种设置最大带宽的系统, 图 5为该系统的连接关系示 意图。 如图 5所示, 该系统包括: 获取装置 10, 用于获取 UE的带宽支持能 力; 上报装置 20, 用于上报所述 UE的带宽支持能力; 授权装置 30, 用于 根据所述 UE的带宽支持能力, 为所述 UE授权与所述带宽支持能力匹配的 最大带宽, 并下发为所述 UE授权的最大带宽。
可选地, 所述获取装置 10, 具体用于从 RNC中获取 UE的带宽支持能 力; 或者从 UE发送的激活上下文消息的 PCO选项中获取 UE的带宽支持能 力。
可选地, 所述上报装置 20, 具体用于缓存已上报的 UE的带宽支持能 力; 如果获取的 UE的带宽支持能力已经上报, 则不再上报; 反之, 上报所 述 UE的带宽支持能力。
所述带宽支持能力包括: 用于指示所述 UE是否支持特定带宽的信息。 根据获得的 UE的带宽支持能力的不同, 本实施例的系统完成的功能也不 同:
( 1 ) 当获取装置 10获取的 UE的带宽支持能力小于所述特定带宽, 或 者 UE支持的版本是某个特定版本之前的版本, 或者获取的 UE的带宽支持 能力为未知, 或者未获取到 UE的带宽支持能力时; 所述授权装置 20, 用 于为所述 UE授权不高于所述特定带宽的最大带宽。
(2) 当获取装置 10获取的 UE的带宽支持能力大于所述特定带宽时; 所述授权装置 20, 用于根据签约信息和 /或运营商策略为 UE授权最大带 宽。
(3 ) 当获取装置 10获取的 UE的带宽支持能力为未知或者未获取到 UE的带宽支持能力后, 再次获取到所述的 UE的带宽支持能力时, 所述授 权装置 20, 用于根据再次获取到的 UE的带宽支持能力, 为所述 UE重新授 权与所述带宽支持能力匹配的最大带宽。
本实施例的系统, 通过获取 UE的带宽支持能力来为 UE授权与其能力 匹配的最大带宽, 能够满足不同类型终端的带宽需求, 充分利用了网络资 源。 有效避免了由于授权的最大带宽高于终端支持的带宽而导致的终端业务 无法建立的问题, 以及由于授权的最大带宽小于终端支持的带宽而导致网络 资源浪费的问题。
实施例 3:

本实施例的系统, 通过获取 UE的带宽支持能力来为 UE授权与其能力 匹配的最大带宽, 能够满足不同类型终端的带宽需求, 充分利用了网络资 源。 有效避免了由于授权的最大带宽高于终端支持的带宽而导致的终端业务 无法建立的问题, 以及由于授权的最大带宽小于终端支持的带宽而导致网络 资源浪费的问题。
下面结合具体的业务流程图来对本实施例系统的工作原理进行解释。 图 7为采用本实施例的系统进行最大带宽设置的详细业务流程图之一。 该流程图适用于 3GPP标准组织定义的 EPS (Evolved Packet System) 系 统, 并且部署了 PCRF, SGW和 PGW之间采用 GTPV2协议, 用户初始接 入时 S4 SGSN已经从 RNC获取到 UE版本信息为 3GPP release 6版本 (不支 持大于 16M QoS参数:)。 如图 7所示:
S70K S4 SGSN从 RNC的 RANAP消息中获取 UE当前支持的版本信 息;
5702、 MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含首次 上下文最大带宽, 本实施例假定该值为 2M;
5703、 S4 SGSN向 SGW发送创建会话请求, 携带 APN AMBR, APN AMBR由 MS请求的首次上下文最大带宽生成, 也可以由 S4 SGSN从 HSS 获取的 EPS签约 QoS profile (profile里含有 APN AMBR参数) 生成 (忽略 UE请求的首次上下文最大带宽), 消息里同时携带 UE当前支持的版本信 息;
注: 因为版本信息仅影响到 QoS授权, 也可以改为其他参数, 比如 UE 是否支持大于带宽超过 16M信息;
5704、 SGW向 PGW发送创建会话请求, 包含 APN AMBR以及 UE当 前支持的版本信息;
5705、 PGW向 PCRF建立 IP-CAN会话, 携带 APN AMBR以及 UE当 前支持的版本信息;
5706、 PCRF授权 APN AMBR, 除了根据 UE当前支持的版本信息, 还 要考虑用户签约、 运营商策略等, 如果 UE当前的版本信息为 R7以前, 则 授权的 APN AMBR要小于等于 16M (在本实施例里假设 MS的 UE版本信 息为 3GPP R6, 则授权的 APN AMBR小于等于 16M) , 通过 IP-CAN会话 建立应答将该授权的 APN AMBR返回给 PGW;
5707、 PGW返回创建会话响应消息, 携带授权的 APN AMBR;
5708、 SGW向 S4 SGSN返回创建会话响应消息;
5709、 S4 SGSN指示 RNC建立无线承载;
5710、 S4 SGSN向 MS返回首次上下文建立响应消息, 针对本实施例 而言授权的 APN AMBR要小于等于 16M。
从图 7可以看出: 对于一个 R7 以前的 UE (不支持大于 16M QoS参 数:), 即使 MS的签约带宽大于 16M, PCRF实际授权也会小于等于 16M, 这就避免了 UE因为返回的 QoS带宽过大, 而导致 UE去激活首次上下文的 问题。
图 8为采用本实施例的系统进行最大带宽设置的详细业务流程图之二。 该流程图适用于 3GPP标准组织定义的 EPS (Evolved Packet System) 系 统, 并且部署了 PCRF, SGW和 PGW之间采用 GTPV2协议, 用户初始接 入时的 S4 SGSN无法从无线接入侧获取到 UE版本信息, 后续 UE移动到一 个新的 S4 SGSN, 该 S4 SGSN可以获取 UE版本信息为 3GPP release 7版本 (支持大于 16M QoS参数), 如图 8所示 (注: 图 8中省略了无线接入网元, 如 2G的 BSS, 3G的: RNC): S80K MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含首次 上下文最大带宽;
5802、 old S4 SGSN向 SGW发送创建会话请求, 携带 APN AMBR, APN AMBR由 MS请求的首次上下文最大带宽生成, 也可以由 old S4 SGSN 从 HSS获取的 EPS签约 QoS profile (profile里含有 APN AMBR参数) 生成 (忽略 UE请求的首次上下文最大带宽:
因为 old S4 SGSN无法获取到 UE的版本信息, 所以 old S4 SGSN携带 的 UE版本信息为未知 (或者 UE支持大于 16M参数未知:), old S4 SGSN也 可不携带任何版本信息参数 (或者 UE支持大于 16M参数)表示未知; SGW 将该消息发送给 PGW;
注: old S4 SGSN无法获取 UE版本信息可能是因为以下三个原因:
A、 用户从 2G无线网络接入, 此时 old S4 SGSN无法从 BSS获取到 UE的版本信息;
B、 用户从 3G无线网络接入, 但是 RNC没有软件升级, 所以 RNC虽 然有 UE版本信息, 但是无法上报给 old S4 SGSN;
C、 用户从无线网络接入并且 RNC支持上报, 但是 old S4 SGSN没有 软件升级, 所以不理解 RNC上报的 UE版本信息。
5803、 PGW向 PCRF建立 IP-CAN会话, 携带 APN AMBR以及 UE当 前支持的版本 0JE支持大于 16M)信息为未知或者不携带版本(UE支持大于 16M)信息;
5804、 PCRF授权 APN AMBR, 并将授权结果通过 IP-CAN会话建立应 答将授权结果返回; 如果 UE当前的版本 (UE支持大于 16M)信息为未知, 为了确保用户肯定能建立首次上下文成功, 则 PCRF授权的 APN AMBR要 小于等于 16M;
S805、 PGW 向 SGW 返回创建会话响应消息, 携带授权的 APN
AMBR, SGW转发该消息给 old S4 SGSN; 5806、 old S4 SGSN指示无线侧建立无线承载 (;图中未画出:)并向 MS返 回首次上下文激活响应消息, 携带的授权首次上下文最大带宽要小于等于 16M;
5807、 后续 UE在 ACTIVE状态切换 (relocation)或者在 IDLE状态移动 (RAU)到一个 new S4 SGSN 的管辖范围(需要说明的是, 虽然改变了 S4
SGSN但本实施例没有 SGW变化:), 该 new S4 SGSN可以从 RNC获取到 UE的版本信息; 比如 UE从 2G网络切换到 3G网络;
5808、 new S4 SGSN向 SGW发送修改承载请求消息, 消息里携带 UE 的版本信息 0JE支持大于 16M信息:
注: 修改承载请求是现有 relocation或者 RAU过程中就有的消息, 本 实施例并没有改变该消息的触发时序, 只是在消息中增添了版本 0JE支持大 于 16M)信息参数;
5809、 SGW判断是否已经上报过 UE的版本 (UE支持大于 16M)信息, 如果已经上报则 S809 以后的歩骤可以省略, 以避免不必要的消息交互。 针 对本例, 因为 SGW 以前上报的版本 (UE支持大于 16M)信息是未知, 而现 在有确定的版本 OJE支持大于 16M)信息, 所以 SGW需要通过修改承载请 求消息把该信息传递给 PGW;
5810、 PGW向 PCRF修改 IP-CAN会话, 携带 UE当前支持的版本 (UE 支持大于 16M)信息;
S811、 PCRF获取到 UE当前支持的版本 (UE支持大于 16M)信息; 重新 授权 APN AMBR, 并将授权结果通过 IP-CAN会话修改应答返回给 PGW。 由于本例 UE支持大于 16M且假设 UE签约的 APN AMBR为 21M, 则 PCRF重新授权的 APN AMBR为 21M;
S812、 PGW向 SGW返回修改承载响应消息;
S813、 SGW向 new S4 SGSN返回修改承载响应消息;
S814— S817、 PGW发起更新承载请求流程, 将 APN AMBR重新修改 为 21M。
从图 8可以看出, 对于一个 R7的终端 (支持大于 16M QoS参数:), 如果 从 2G网络接入 (或者是不支持上报 UE版本的 3G网络接入:), 初始时虽然授 权的 QoS小于 16M, 但当 R7的终端移动到支持 UE版本上报的 3G网络, 则 PCRF会重新授权, 使得 R7的终端可以享受高于 16M的高带宽业务。
图 9为采用本实施例的系统进行最大带宽设置的详细业务流程图之三。 该流程图适用于 3GPP标准组织定义的 EPS (Evolved Packet System) 系 统, 并且部署了 PCRF, SGW和 PGW之间采用 GTPV2协议, 用户初始接 入时的 S4 SGSN可以从无线接入侧获取到版本信息, 后续 UE移动到一个 新的 S4 SGSN, 该 S4 SGSN同样可以获取 UE版本信息为 3GPP release 6版 本 (;不支持大于 16M QoS参数: ); 如图 9所示:
S901-S906与图 8中相应的歩骤相同, 不再赘述;
5907、 后续 UE在 ACTIVE状态切换 (relocation)或者在 IDLE状态移动 (RAU)到一个 new S4 SGSN管辖范围 (;本例里新的 S4SGSN会选择一个新的 SGW),该 new S4 SGSN也可以从 RNC获取到 UE的版本信息;
5908、 新的 S4 SGSN向新的 SGW发送创建会话请求消息, 消息里携 带 UE的版本 (UE不支持大于 16M)信息;
5909、 因为是切换流程, 新的 SGW 向 PGW发送修改承载请求指示 PGW切换到新的 SGW, 同时消息里携带 UE的版本 (UE不支持大于 16M) 信息;
5910、 PGW判断已经向 PCRF上报过版本 (UE不支持大于 16M)信息, 则不再向 PCRF发送 IP-CAN会话修改消息 (不需要重新授权 QoS); 直接向 SGW返回修改承载请求响应;
5911、 SGW向 new S4 SGSN返回修改承载请求响应。
从图 9可以看出, 一旦 S4 SGSN上报了 UE的版本 (UE是否支持大于
16M)信息后, 即使 UE移动到新的 S4 SGSN, 无论新的 S4 SGSN是否支持 获取 UE版本, 都不需要重新授权 QoS, 这样就避免了不必要的信令交互, 节省了网络资源。
图 10为采用本实施例的系统进行最大带宽设置的详细业务流程图之 四。 该流程图适用于 3GPP标准组织定义的 EPS (Evolved Packet System) 系统, 与图 7不同的是 SGW和 PGW之间采用 PMIP协议而不是 GTPV2协 议, 在这种情况下 SGW无法通过 PMIP消息将 UE版本 (是否支持大于 16M)信息传递给 PGW, 而是由 SGW通过和 PCRF之间的网关控制会话将 该信息传递给 PCRF; 如图 10所示:
S100K MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含首 次上下文最大带宽;
51002, S4 SGSN向 SGW发送创建会话请求, 携带 APN AMBR, APN AMBR由 MS请求的首次上下文最大带宽生成, 也可以由 S4 SGSN获取的 EPS签约 QoS profile (profile里含有 APN AMBR参数) 生成 (忽略 UE请求 的首次上下文最大带宽:), 消息里同时携带 UE当前支持的版本 (UE是否支持 大于 16M)信息;
注: 本实施例省略了从 RNC获取版本信息的歩骤;
51003、 SGW向 PCRF发送创建网关控制会话请求, 包含 APN AMBR 以及 UE当前支持的版本信息;
51004, PCRF授权 APN AMBR, 并将授权结果通过网关控制会话建立 应答返回给 SGW, 其中, 所述授权, 除了根据 UE当前支持的版本信息, 还要考虑用户签约、 运营商策略等, 如果 UE当前的版本信息为 R7以前, 则授权的 APN AMBR要小于等于 16M;
51005、 SGW向 PGW发送绑定更新请求消息, 指示 PGW建立到 SGW 的数据连接;
S1006、 PGW向 PCRF建立 IP-CAN会话;
SI 007、 PCRF向 PGW返回在歩骤 SI 004已经授权的 APN AMBR; 51008、 PGW向 SGW返回绑定更新应答消息;
51009、 SGW向 S4 SGSN返回创建会话响应消息, 携带歩骤 S1004返 回的授权 APN AMBR;
51010、 S4 SGSN向 MS返回首次上下文建立响应消息, 针对本例而言 授权的首次上下文最大带宽要小于等于 16M。
从图 10可以看出, 如果初始时 S4 SGSN无法获取版本信息后续移动到 新的 S4 SGSN能够获取版本信息, 新的 S4 SGSN会把版本信息传递给 SGW贝 I」 SGW也要通过和 PCRF之间的网关控制会话上报版本信息, 由 PCRF重新授权, PCRF会把新的授权值返回给 SGW和 PGW, 其过程和图 8类似, 此处不再赘述。 实施例 4: 本实施例提供一种设置最大带宽的系统, 再次参考图 6, 所述系统包 括: PGW, 用于从 UE发送的激活上下文消息的 PCO选项中获取 UE的带 宽支持能力, 并将所述 UE的带宽支持能力上报给 PCRF; 所述 PCRF, 用 于根据所述 UE的带宽支持能力, 为所述 UE授权与所述带宽支持能力匹配 的最大带宽, 并下发为所述 UE授权的最大带宽。
所述系统还包括: SGSN, 用于接收 UE发送的所述激活上下文消息并 将所述消息透传给 SGW; SGW, 用于接收所述 SGSN发送的所述激活上下 文消息并将所述消息透传给所述 PGW。
图 11 为采用本实施例的系统进行最大带宽设置的详细业务流程图。 该 流程图适用于 3GPP标准组织定义的 EPS (Evolved Packet System) 系统, 与图 7不同的是该流程图由 MS 自己通过扩展 PCO(Protocol Configuration Options), 将 UE的版本 (是否支持大于 16M)信息传递给 PGW, 中间网元、 S4 SGSN和 SGW不需理解 PCO; 如图 11所示:
S110K MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含请 求首次上下文最大带宽, 同时携带 PCO选项, 选项里包含 UE的版本 (是否 支持大于 16M)信息;
51102、 S4 SGSN向 SGW发送创建会话请求, 携带 APN AMBR, APN AMBR由 MS请求的首次上下文最大带宽生成, 也可以由 S4 SGSN获取的 EPS签约 QoS profile (profile里含有 APN AMBR参数) 生成 (忽略 UE请求 的首次上下文最大带宽:), 消息里同时携带 PCO选项;
51103、 SGW向 PGW发送创建会话请求, 包含 APN AMBR和 PCO选 项;
51104、 PGW向 PCRF建立 IP-CAN会话, 携带 APN AMBR以及从 PCO里提取的 UE当前支持的版本 (是否支持大于 16M)信息;
51105、 PCRF授权 APN AMBR, 并将授权结果通过 IP-CAN会话建立 应答返回给 PGW, 其中, 所述授权除了考虑用户签约、 运营商策略等, 还 要根据 UE当前支持的版本信息, 如果 UE当前的版本 (是否支持大于 16M) 信息为 R7 以前或者不支持大于 16M, 则授权的 APN AMBR要小于等于 16M; 如果 PGW没有上报 UE当前的版本 (是否支持大于 16M)信息, 则为 了确保 MS能够激活成功, 授权的 APN AMBR也要小于等于 16M; 具体到 本例, UE不支持大于 16M且 UE的签约 APN AMBR小于 16M, 则 PCRF 授权的 APN AMBR小于或等于 16M;
51106、 PGW返回创建会话响应消息, 携带授权的缺省承载 QoS和 APN AMBR;
SI 107、 SGW向 S4 SGSN返回创建会话响应消息;
51108、 S4 SGSN指示 RNC建立无线承载;
51109、 S4 SGSN向 MS返回首次上下文建立响应消息, 针对本例而言 授权的 APN AMBR要小于等于 16M。
从图 11可以看出, 如果是 MS 自己携带 UE版本信息, 则不会存在如 实施例 2所述的从未知到已知的场景, 因为 MS要么支持上报要么不支持上 报, 不会存在变化的场景。 实施例 5 : 本实施例提供一种设置最大带宽的系统。 图 12为该系统的连接关系示 意图。 如图 12所示, 该系统包括: SGSN, 用于获取 UE的带宽支持能力, 并向 GGSN上报所述 UE的带宽支持能力; GGSN, 用于根据所述 UE的带 宽支持能力, 为所述 UE授权与所述带宽支持能力匹配的最大带宽, 并下发 为所述 UE授权的最大带宽。
可选地, 所述 SGSN, 具体用于从 RNC中获取 UE的带宽支持能力。 图 13为采用本实施例的系统进行最大带宽设置的详细业务流程图。 该 流程图适用于 3GPP标准组织定义的 GPRS (General Packet Radio Service) 系统, 没有部署 PCRF , 用户初始接入时的 SGSN (仅支持 GTPV1 的 SGSN), 可以从无线接入侧获取到版本信息。 如图 13所示:
S130K SGSN从 RNC 的 RANAP消息中获取 UE当前支持的版本信 息;
S1302、 MS发起首次上下文激活过程, 携带请求的 QoS参数, 包含请 求首次上下文最大带宽;
51303、 SGSN向 GGSN发送创建上下文请求, 携带协商的 QoS参数, 协商的 QoS参数包含首次上下文最大带宽, 最大带宽可以由 MS请求的首 次上下文最大带宽生成, 也可以由 SGSN获取的 GPRS签约 QoS profile (profile里包含首次上下文最大带宽参数) 生成, 消息里同时携带 UE当前 支持的版本信息;
注: 因为版本信息仅影响到 QoS授权, 也可以改为其他参数, 比如 UE 是否支持带宽大于 16M信息;
51304、 GGSN根据请求消息里协商的 QoS信息和 UE版本 (是否支持大 于 16M)信息, 决定返回消息里的协商 QoS参数, 包含首次上下文最大带 宽; 如果 UE版本信息为 Release以前或者不支持大于 16M, 即使请求消息 里的协商 QoS最大带宽超过 16M, 但在返回消息里的协商 QoS最大带宽要 小于等于 16M;
S1305、 SGSN指示 RNC建立无线承载;
S1306、 SGSN 向 MS返回首次上下文建立响应消息, 针对本例而言授 权的 MBR要小于等于 16M;
注 1 : 本例中的 GGSN也可以是同时支持 GTPV1和 GTPV2的合一节 点 (如 PGW);
注 2: 在 GPRS系统里也有 SGSN无法获取 UE版本信息的情况, 处理 和图 8和图 9类似, 此处不再赘述。 实施例 6: 本实施例提供一种设置最大带宽的装置, 图 14为该装置的功能框图, 如图 14所示, 该装置包括: 获取单元 1401, 用于获取 UE的带宽支持能 力; 授权单元 1402, 用于根据所述 UE的带宽支持能力, 为所述 UE授权与 所述带宽支持能力匹配的最大带宽, 并下发为所述 UE授权的最大带宽。
可选地, 所述带宽支持能力包括: 用于指示所述 UE是否支持特定带宽 的信息或者 UE支持的版本信息; 根据获取的带宽支持能力的不同, 本实施 例的装置完成不同的授权过程:
( 1 ) 当所述获取单元 1401获取的 UE的带宽支持能力小于所述特定带 宽, 或者 UE支持的版本是某个特定版本之前的版本, 或者获取的 UE的带 宽支持能力未知, 或者未获取到 UE 的带宽支持能力时; 所述授权单元 1402, 用于为所述 UE授权不高于所述特定带宽的最大带宽。
(2) 当所述获取单元 1401获取的 UE的带宽支持能力大于所述特定带 宽时; 所述授权单元 1402, 用于根据签约信息和 /或运营商策略为 UE授权 最大带宽。 (3 ) 当所述获取单元 1401获取的 UE的带宽支持能力未知, 或者未获 取到 UE的带宽支持能力后, 再次获取到所述 UE的带宽支持能力时, 所述 授权单元 1402, 用于根据再次获取到的 UE的带宽支持能力, 为所述 UE重 新授权与所述带宽支持能力匹配的最大带宽。
本实施例的装置可以是前述实施例的 PCRF设备或者是 GGSN设备, 还可以是能够实现等同功能的其他网络设备。 实施例 7: 本发明实施例提供一种设置最大带宽的方法, 该方法对应于实施例的装 置, 图 15为该方法的整体流程图, 如图 15所示, 该方法包括:
S150K 获取 UE的带宽支持能力;
S1502, 根据所述 UE的带宽支持能力, 为所述 UE授权与所述带宽支 持能力匹配的最大带宽, 并下发为所述 UE授权的最大带宽。
可选地, 所述带宽支持能力包括: 用于指示所述 UE是否支持特定带宽 的信息或者 UE支持的版本信息。
根据获取的 UE的带宽支持能力不同, 本实施例采用不同的授权方式:
( 1 ) 当获取的 UE的带宽支持能力小于所述特定带宽, 或者 UE支持 的版本是某个特定版本之前的版本, 或者获取的 UE的带宽支持能力未知, 或者未获取到 UE的带宽支持能力时; 为所述 UE授权不高于所述特定带宽 的最大带宽。
(2) 当获取的 UE的带宽支持能力大于所述特定带宽时; 根据签约信 息和 /或运营商策略为 UE授权最大带宽。
(3 ) 当获取的 UE的带宽支持能力未知, 或者未获取到 UE的带宽支 持能力后, 再次获取到所述 UE的带宽支持能力时; 根据再次获取到的 UE 的带宽支持能力, 为所述 UE重新授权与所述带宽支持能力匹配的最大带 宽。 综上所述, 本发明实施例的技术方案采用以下几点来实现 UE最大带宽 的设置:
1、 SGSN从 RNC获取 UE当前支持的版本信息, 通过现有的信令将其 传递给 PGW/GGSN/PCRF; 或者 UE扩展激活上下文消息中的 PCO选项, 将 UE 当前支持的 3GPP 版本(是否支持大于 16M)信息传递给 PGW/GGSN/PCRF;
2、 PGW/GGSN/PCRF根据 UE当前支持的版本 (是否支持大于 16M)信 息进行 QoS授权, 如果 UE当前支持的 3GPP版本为 release 7以前 (不支持 大于 16M)或者 PGW/GGSN/PCRF没有得到 UE当前支持的 3GPP版本 (;是否 支持大于 16M)信息, 则授权的最大带宽要小于等于 16M;
3、 可选的, PGW/GGSN/PCRF在不知道 UE支持的版本信息的情况下 授权 QoS后, 又得到了 UE当前支持的版本 (是否支持大于 16M)信息, 则 PGW/GGSN/PCRF需要重新授权最大带宽;
4、 为了避免重复上报 UE当前支持的 3GPP版本 (是否支持大于 16M)信 息, SGW/PGW需要缓存已经上报过的 UE 的 3GPP版本 (是否支持大于
16M)信息, 对于已经上报过的, 则不需要再次上报。
本发明实施例的技术方案通过获取 UE的带宽支持能力来为 UE授权与 其能力匹配的最大带宽, 能够满足不同类型终端的带宽需求, 充分利用了网 络资源; 能够解决 3G无线网络升级到 HSPA+后, 网络支持大于 16M的
QoS , 但是由于部分终端不支持带宽大于 16M参数而网络侧授权的带宽大 于 16M引起的 PDP上下文无法激活从而无法实现数据业务的问题。
本领域普通技术人员可以理解: 实现上述方法实施例的全部或部分歩骤 可以通过程序指令相关的硬件来完成, 前述的程序可以存储于一计算机可读 取存储介质中, 该程序在执行时, 执行包括上述方法实施例的歩骤, 而前述 的存储介质包括: ROM、 RAM, 磁碟或者光盘等各种可以存储程序代码的 介质。
以上实施例仅用以说明本发明实施例的技术方案, 而非对其限制; 尽管 参照前述实施例对本发明实施例进行了详细的说明, 本领域的普通技术人员 应当理解: 其依然可以对前述各实施例所记载的技术方案进行修改, 或者对 其中部分技术特征进行等同替换; 而这些修改或者替换, 并不使相应技术方 案的本质脱离本发明实施例各实施例技术方案的精神和范围。
